A photofacial is a procedure in which intense pulses of light are used to penetrate deep into the skin. IPL™ photorejuvenation then causes collagen and blood vessels below the epidermis to constrict, reducing redness and fine lines. The procedure involves only minimal discomfort, while the redness and swelling that sometimes occur after treatment disappear shortly. Most benefits of a photofacial occur gradually in the weeks following treatment. Certain pigmented lesions can be treated with this form of light.
